Energy reduction in 3D NoCs through communication optimization

Cataloged from PDF version of article.Network-on-Chip (NoC) architectures and three-dimensional (3D) integrated circuits have been introduced as attractive options for overcoming the barriers in interconnect scaling while increasing the number of cores. Combining these two approaches is expected to yield better performance and higher scalability. This paper explores the possibility of combining these two techniques in a heterogeneity aware fashion. Specifically, on a heterogeneous 3D NoC architecture, we explore how different types of processors can be optimally placed to minimize data access costs. Moreover, we select the optimal set of links with optimal voltage levels. The experimental results indicate significant savings in energy consumption across a wide range of values of our major simulation parameters

Design of Networks on Chips for 3D ICs

Three-dimensional integrated circuits, where multiple silicon layers are stacked vertically have emerged recently. The3DICs have smaller form factor, shorter and efficient use of wires and allow integration of diverse technologies in the same device. The use of Networks on Chips (NoCs) to connect components in a 3D chip is a necessity. In this short paper, we present an outline on designing application-specific NoCs for 3D ICs
